IMPROVED APPARATUS FOR MIXING MORTAR FOB MAKING-BUIIiDING-BLOOKc.

die assault aferra tu in that tetta patent ma making satt si its sind To ALLWHOM 1m MAY ooNonaN= Be it'known that I, JOHN SHELLEY, of Harlem, in the county and State-of 'New York, have invented certain new and useful Improvements in Machinery and Apparatus for Mixing Lime and 4Sand for' Making Building-Blocks and for other purposes; and the following isa full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which-f Figure 1 represents a side elevation of the apparatus'or machine for mixing lime and sand.

Figure 2 shows an end-view elevation Voi` the same, with'the water and steam pipes and stop-cocks. v

Figure 3 is a plan of the rotating cylinder with the top or one-half of the cylinder removed, `showing the internal arrangement of 'the pipe for admitting both the steam and thewateigand the scrapers to prevent the silicate from adhering to the ends and inside of the cylinder.

The object of my invention is to thoroughly mix lime and sand and .produce a mortar for making buildingblocks.

My invention consists in the introduction of steam, and also the requisite quantity of Water, through the same pipe, into the centre of the rotating-cylinder, distributing it evenly, While it is revolving, throughout lthe entire mass; also in securing to the steam and water pipe stationary frames and blades for cutting and mixing and preventing the mortar from adhering to the ends and inner portion of the cylinder; likewise-in the arrange ment of the water-tanks, stop-cocks, and pipes, so that either steam or Water may be forced into the cylinder at one orat both'ends at the same time. f l

To enable others to make and 'use .my invention, I will describe it more fully, referring to the drawings', and to lthe letters marked thereon.

I make the cylinder A of strong boiler-iron, or it may have cast-iron heads B B with Ihollow trunnions i or journals to run on, they being fitted into metal lioxes C C, so as to sustain'the heavy weight in the cylinder A and yet turn easily. On one end of ltlfe cylinder A I have a spur-gear, a a, surrounding it, and a pinion, c, on a shaft, al, with pulleys D to drive and rotate the cylinder A. Through `the centre of the cylinder A is a hollow pipe, E, extending out throughjhoth of the hollow trunnions b b, with elbowjoints e e, into-which the water pipes F F are fitted and connect with the water-tanks Gr G, which areelevated to a suitable height above.

them, so that the Water 'vill be forcedinto the cylinderA when the cocks ff are turned to admit it. Connected with the Water pipes F F are the steam pipes H H,with their stop-cocks k i, so that the steam from the boiler can be admitted into the cylinder A under any desired pressure, and controlled by the stop-cocks L 7L at pleasure, either from one or both ends of the cylinder; the arrangement 'being such that either water or steam may t be alternately let in or shut off from the cylinder, as the necessities may require. The'hollow' pipe E, which extends through the centre of the cylinder A, is perforated .with holes on its under side to let the steam and water escape, While none oi' lthe ingredients contained in the cylinder will be likely to get into -the pipe'to obstruct it. '.lo the pipe E are secured arms z'z' z' z', extending out at right angles to near the internal diameter of thecylinder A, on the ends of which-are fastened longitudinal bars or Scrapers I I, which, being stationary, come so near the cylinder as to prevent the mixture of the lime and sand from adhering to the inner surface as the cylinder A is revolving, While the process of mixing is going on.

In arranging the cylinder A and theother fixtures fornpreparing the material to be compressed into arti=l iicial stone or building-blocks5- if it is not convenient to have the water-tanks G Gr elevated to a sulicieut height to force the water into the cylinder A, they may be provided with pipesconnecting. the steam-boiler with the tops oi' the wa'ter-tanks, they having covers {itted steam-tight, so that the water can be forced in by the pressure of steam, thereby makingthe apparatus very compactly arranged and complete in its operation.

It will. readily be seen thatby my arrangement for admitting hoth steamaud water into the cylinder whilev it is revolving and the sulstancel it contains is in" motion; the ingredients cannot fail. 'to become thoroughly mixed and the process of calcinatiou will be much more rapid and perfect, Whichis amatter that experience has taught 'to be 'of the greatest importance in the process of preparing the lime and sand for mouldinginto building-blocks or artificial stone.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters ]?atent, is"-` 1. I claim thc stationary hollow pipe E, passing through theY trunnions b band extending longitudinally through the centre of the cylinder A, to which the water and 'steam pipes areboth connected, the same being i provided with holes or outlets on the under side, as herein described.

2.V In combination with `the stationary pipe E, the arms and Scrapers or blades I I, I claim the revolving cylinder A, operating in the manner as herein described, for the purposes set forth. v

3. I claim the arrangement ofthe Water-tanks G Gr, the connecting water and steam pipes H H, with their stop-cocks L h placed at one or at both ends of the revolving cylinder, so that both steam and water may be alternately introducedinto the mixture, substantially in the manner as herein set forth.

' JOI-IN SHELLEY.
